Du Fu Digital Security (杜浦數位安全), a threat intelligence firm specializing in the Asia-Pacific region, participated in the 2025 Taiwan Cybersecurity Conference. Founder Tsai Song-Ting reported that following recent attacks on two medical institutions by the Crazy Hunter group, several other enterprises have also been targeted. TeamT5 identified and alerted multiple affected entities through specialized methods, assisting five companies in preventing potential attacks.
Tsai emphasized that “Team TAIWAN,” the brand name of TeamT5, prioritizes intelligence gathering under its slogan: "Full Defense for Taiwan." He drew a parallel between cybersecurity defense strategies and baseball tactics, highlighting the importance of understanding an opponent's strengths to develop effective countermeasures. Utilizing threat intelligence can significantly enhance defensive measures, providing comprehensive protection against cyber threats.
Drawing further on this analogy, Tsai explained that just as deploying defenses based on player habits and performance minimizes strategic errors in baseball, leveraging threat intelligence helps build robust technical foundations for enterprises facing network attacks. He underscored the importance of cultivating threat intelligence capabilities among cybersecurity professionals to ensure effective defense strategies.
TeamT5’s observations indicate a growing interest from Chinese hacker groups targeting medical institutions, though their focus ultimately lies on any organization capable of paying ransom. Tsai noted that common software and cloud services used by Taiwanese companies are also vulnerable targets; therefore, enterprises must promptly patch recently exploited vulnerabilities—such as those leveraged by the Crazy Hunter group.
For organizations experiencing breaches, TeamT5 provides rapid assistance with cleanup efforts while continuously monitoring them for further attacks or data theft (APT). The company’s extensive two-decade research on Chinese hacker activities has established it as a key player in both Japan and Southeast Asia markets, currently accounting for 40% of its overseas revenue.
